The actress, who welcomed baby Noah in September, sent her first tweet late Thursday afternoon, not long after "RIP Megan Fox" — a web death hoax — was trending. She didn't mention the death report, however.

"I'm incredibly late to the party," Fox wrote, "but I'm here nonetheless, so what now?"

Fox, 26, who is active on Facebook, has more than 35,000 followers, and is following exactly 0 people at this point.
